1984 Alabama Cotton Variety Report
A Report of the Performance of Cotton 
Varieties Tested in Alabama

and Darrell

INTRODUCTION
The Alabama Cotton 
Variety Test is a 
continuing evaluation 
of avail-
able cotton varieties 
from private companies 
and state agricultural 
experi-
ment stations. Breeding 
lines that are likely to 
be released as varieties
are also tested. Tests 
are conducted on units 
of the Alabama Agricultural
Experiment Station by Experiment 
Station personnel. Cultural 
practices are
those generally recommended 
by Auburn University to 
farmers. Every effort
is made to test the varieties 
and present the results 
in an unbiased
Smanner.
EXPERIMENTALo CONDITIONS
A randomized block experimental 
design with four replications 
was used
at each location. Plot row 
length at different locations 
varied from 40 to
120 feet. Plots were two-row 
at Prattville, Headland, 
Belle Mina, and
Crossville. Single-row 
plots were used at the other 
locations. Climatic
conditions were near ideal 
for cotton production as indicated 
by an average
yield of 1,130 pounds 
lint per acre for all 1984 
variety tests in Alabama.
EXPLANATION OF DATA
Harvest of Seed Cotton
Tests at Prattville, Brewton, 
Monroeville, Tallassee, Belle 
Mina, and
Shorter were harvested by 
a mechanical spindle picker. 
Tests at Headland
1
Respectively, Professor and 
Research Associate of Agronomy 
and Soils.
1
and Crossville were harvested by hand. Average yield of seed cotton was
determined for each variety at each location.
Lint Percentage
A sample of seed cotton from each variety at each location was taken
at harvest and ginned on a 10-saw gin. Lint percentage was calculated by
dividing weight of lint by weight of seed cotton. Lint percentage may be
higher than that obtained at commercial gins because the 10-saw gin has no
cleaning equipment.
Yield of Lint
Lint yield was determined by multiplying the lint percentage by yield
of seed cotton.
Fiber Properties
Fiber qualities of all varieties from selected locations were deter-
mined by Starlab, a commercial fiber testing laboratory in Knoxville,
Tennessee.
Span Length. This is the fiber length measured with the digital
fibrograph. The 2.5 percent length is the average length of the longest
2.5 percent of the fibers and the 50 percent length is the average length
of the longest 50 percent of the fibers. Their ratio is an expression of
the fiber length uniformity. The 2.5 percent length is about the same as
the classer's staple.
Stelometer. T
1 
is a measure of breaking strength of a standard fiber
bundle with the holding jaws separated by 1/8 inch. This is a measurement
similar to Pressley strength except the figures are in grams per tex. Tex
is a size measurement of the fiber bundle. The larger the T
1
, the stronger
the fibers. El measures the percentage stretch before the fibers break.
2
Micronaire. This measures the fineness and maturity of the cotton
fibers. The smaller the micronaire reading, the finer and/or more immature
the fibers. The desirable range of micronaire is 3.5 to 4.9.
Earliness
Where more than one harvest was made, earliness is reported as the
percentage of the total yield harvested at the first picking.
Fusarium wilt
Reaction of varieties to Fusarium oxysporum f. vasinfectum (fusarium
wilt) was evaluated at the Plant Breeding Unit, Tallassee. The varieties
were grown in a field with a high natural incidence of the fusarium
wilt disease. Severity of the disease varies from year to year and also
within the experimental area in the same year. Therefore, several years'
data are necessary to realistically characterize a variety's wilt reaction.
Stoneville 213 and Stoneville 825 have consistently shown a high incidence
of wilt. All other reported varieties that have been tested for at least 3
years have acceptable tolerance to fusarium wilt.
NEW AND EXPERIMENTAL VARIETIES
PD 4548 is an experimental line from the Pee Dee Experiment Station,
Florence, South Carolina, that has just been released as a variety and
named .PD-1. Breeder seed are available from the Pee Dee Experiment
Station. Deltapine 50 is a new variety, released in 1985, which we have
tested several years. Deltapine 69, previously designated Deltapine 733,
has been released but seed are not yet generally available. Deltapine 102
is an advanced experimental strain. Coker 81-102 is a high Quality
advanced strain which has not been released and for which seed are not yet
available. GAT 72-56 is an experimental strain from Tifton, Georgia, and
3
Acala SJ C-1 and Paymaster 145 are varieties adapted 
to the Western United
States. These are included in certain Alabama tests 
as part of a national
variety testing program.
STATISTICAL ANALYSIS
Appropriate analyses of the yield data were made. For each location,
the variability in the test was measured and expressed as a percentage of
the test mean, i.e., the coefficient of variation (C.V.). 
An indication of
the magnitude of difference between variety averages necessary 
to be
considered a real difference is given for each location. 
It is designated
Least Significant Difference (L.S.D..
05
).

RECOMMENDED COTTON VARIETIES FOR ALA8AMA
The list of recommended varieties given below was prepared by a
committee composed of the authors of this report and Dr. Louie J. Chapman,
Head of Extension Agronomy, Alabama Cooperative Extension Service, based on
variety test performance for at least 3 years. Varieties differ in perfor-
mance at individual locations, so selection should be based largely on
variety performance at a site that most nearly represents the grower's
local situation. The recommended varieties are listed in order of 3-year
average lint yield.
